Torsion hitch for tractor with fence mower

Abstract

A system consisting of a versatile hitch attached to a tractor which positions a ground-based implement, such as a mower, in front or to either side of the tractor. The hitch cushions or dampens movement using a torsional component over rough ground by the tractor allowing the implement to traverse a near parallel ground direction. The mower design mows either normally over open ground or in restricted locations, such as around fences supported by posts.

I claim: 
     
       1. A hitch mounted on a tractor containing a power system for controlling a ground-based implement, comprising: a longitudinally adjustable assembly, working in conjunction with said power system, which has sufficient capacity to handle movement of said ground-based implement, and which is structurally pivotally connected to said tractor; and   means for providing a flexible dampening mechanism, which is stiffness adjustable, structurally connected between said longitudinally adjustable assembly and said ground-based implement.   
     
     
       2. The hitch according to claim 1 wherein said longitudinally adjustable assembly further comprises a hydraulic piston and cylinder mechanism. 
     
     
       3. The hitch according to claim 1 wherein said flexible dampening mechanism further comprises a stretchable load-bearing cover partially encompassing said longitudinally adjustable assembly, wherein the upper portion of said stretchable load-bearing cover is structurally attached to the boom of said longitudinally adjustable assembly. 
     
     
       4. The hitch according to claim 3 wherein said stretchable load-bearing cover further comprises a plurality of spiral springs. 
     
     
       5. The hitch according to claim 1 wherein said flexible dampening mechanism further comprises a torsional device structurally mounted between the boom of said longitudinally adjustable assembly and said ground-based implement. 
     
     
       6. The hitch according to claim 5 wherein said torsional device further comprises being selected from the group consisting of adjustable torsional bars, adjustable torsional springs, adjustable rubber torsional axials, and combinations thereof.
